DIRIGIBLE HEADLIGHT.

Specification of Letters Patent.

Patented Oct. 14,1913.

Application filed. August 2, 1912. Serial No. 712,949.

To all whom it may concern Be it known that I, ERNST I-Iomvrson, a citizen of the United States, residing at Edgar, in the county of Marathon, State of lVisconsin, have invented certain new and useful Improvements in Dirigible Headlights; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to locomotive dirigible headlights and has for an object to provide a headlight equipped with novel means for automatically turning the headlight in the direction of movement of the locomotive in rounding a turn so that the light is at all times thrown direct ahead upon the track.

A further object of the invention is to provide a flexible connection between the headlight turning mechanism and the pilot truck of the locomotive so that the mechanism will not be injured by the jumping or bouncing of the locomotive.

With the above objects in view the invention consists of certain novel details of construction and combination of parts hereinafter fully described and claimed, it being understood that various modifications may be made in the minor details of construction within the scope of the appended claim.

In the accompanying drawings forming part of this specification :-Figure 1 is a side elevation of the front portion of a locomotive equipped with my improvements. Fig. 2 is a front elevation of the locomotive with the cow catcher removed to expose the invention. Fig. 8 is a plan view of the device. Fig. 4 is a cross sectional view taken on the line H Fig. 1.

Referring now to the like characters of reference lar parts, 10 designates the leading portion of a locomotive. As usual the pilot truck 11 swings upon a pivot in rounding turns. For swinging the head-light 12 simultaneously with and in the direction of the pilot truck, the following mechanism is employed.

Secured to the pilot truck is abracket arm drawings in which deslgnate sum- 13 which is upturned abruptly at the outer end as shown at 14: and is terminally equipped with an oblong frame 15 the long axis of which is horizontal and extends parallel with the long axis of the locomotive. The headlight 12 is swivelly mounted on the boiler in any preferred manner and is equipped on the rear side with hinge ears 16 between which one end of a shifting lever 17 is interposed and is pivotally secured by means of a pivot pin.

A rock link 19 is pivoted intermediate the ends upon a bracket arm 20 which is secured to the boiler of the engine or other suitable stationary support. The rock le ver extends in upright position along the side of the locomotive boiler and is pivotally connected at the upper end to the outer end of the shifting lever by a pivot pin 21. The lower end of the rock link projects into the oblong frame 15 carried by the pilot truck, and is terminally equipped with a roller bearing 22 which rides upon the inner walls of the frame as clearly shown in Fig. 1.

In rounding a turn when the pilot truck is swung lateral the oblong frame will be likewise swung simultaneously with the pilot truck and will carry the lower end of the rock link in the same direction as the truck is swung. The upper end of the rock link is swung in an opposite direction from the truck and carries the shifting lever with it with a resultant swiveling of the headlight in the same direction as the truck is swung. Thus the ray of light is at all times shown direct ahead upon the track whether the locomotive is traveling upon a straight track or swinging around a turn.

What is claimed is The combination with a turning headlight, an engine boiler, and a turning pilot truck, of a bracket fixed to said truck and having a horizontally disposed oblong frame extending longitudinally of and outside of one side of said truck, an upwardly extending rock lever fulcrumed intermediate the ends on the boiler side and rockable transversely with respect to the longitudinal axis of said boiler, a roller bearing on the lower end of said lever riding longitusaid headlight simultaneously with and in the same direction as said truck. 10

In testimony whereof, I aifix my signature, in presence of two Witnesses.
